starting problem aq130 c

sunday we were out fishing. fished on the kicker. when we went to fire up the aq130 it did not seem to want to start. oil pressure gauge and temp gauge were hard over to the right and fuel gauge did not show fuel at all. thought I had a dead battery because of a short. started home on the kicker and on the way tried lifting the leg to see if it would give a little more speed. while it was up I tried the starter again and it fired right up. now I,m home and trying to figure what my issue is. gauges still right over when I turn on key and starter sounds like a dead battery issue until I touch the lift switch and the light comes on , then it starts right up. any help would be greatly appreciated.
 
Check all your grounds. Sounds like the starter is picking up it's ground from the lift motor. The starter needs a good clean surface when it mounts to the flywheel case to complete the circuit. Load test the battery while you're at it.
 
I'm not seeing any correlation between the lift out unit motor and the starter motor function.
The lift out unit motor has its own separate lighter gauge positive and negative cables.
The transom shield and the spendle arm are bonded to the engine block with a green number 10 wire....... which is not heavy enough to support the starter motor load.

I do agree with Gary in that you need to look at the negative cable connections as well as a positive cable connections on any 12 V system.

Also, you may want to check the continuity of your MBSS. If Perko 90* sweep, these have rather small contacts and a light spring load.

Both starter motor AND starter solenoid need good grounds. The solenoid ground is kissing cousin to the instrument ground but not the exact same point.
 
Thank You for your input. I will check and see what I can find when I go home for lunch today. I had a feeling thee is a ground issue somewhere with the leg somehow . now I at least have some kind of starting point.
 
Well so much for my starting point. I now believe it to be my instrument ground. I did find a couple grounds that were loose but also found when the bilge pump or blower were on it started also, but now I have no running lights or wiper. I love boats and boating, I love boats and boating, I love.......
 
Doug, it's likely to be a strange coincidence that the starter motor engages as you raise the drive up.
The only electrical component regarding your drive, is the lift out unit electric motor and the relay switching mechanism.
As I said earlier, the lift out unit has its own small gauge positive and negative conductors running to it.
Neither of these leads are heavy enough to carry a starter motor load.

Look at the inside of the transom near the starboard side for your main harness/engine harness connector fitting.
All of your engine circuits are in this harness, including the starter motor solenoid circuit.
Pull this connector apart and examine the contact terminals. Pull it apart and push it back together several times.

The solenoid circuit will be a yellow wire ..... possibly with a red stripe. Run a continuity check on this circuit within the main harness fitting, and then directly at this same circuit at starter motor solenoid.

Thanks Rick,
I think I have it arrowed down to the lower circuit and the wiper circuit. turn on the wipers an the blower comes on though not full power. the wiring has been butchered by the previous owner. I have power in the negative wire to he wiper and that is tied in to the blower switch. after dinner I will run new wire and I think that will solve the problem.
 
well it starts properly wiper works, bilge pump works, gauges work. that's it for tonight. blower works but shorts gauges and no running lights.
 
Rick, I'm pretty sure the start wire on the old 130's is white and there is no slave solenoid, just the solenoid on the starter itself. The way this boat is acting it's got to be a ground or something back feeding.

I'm thinking yellow... and that white has been the tachometer color for years. But I could be wrong though.

Correct. I was refering the solenoid on the motor itself.

Well, I agree that electrical problems can be strange and weird.

A lot of the trouble with this motor and drive come from the fact that it was not factory setup. the previous owner did the install and wiring thus not everything matches the manual. I knew I should not buy this boat but I was a good deal IF I could do most of the work. so far I think I,m still ahead.
